[platform-swt-dev] Alignment Problems with ExpandBar within SashBar

Whenever I put anything in an ExpandBar within a SashBar, the alignment is weird whenever it is expanded. As you can see from the demo I attached, the StyledText box's left border is too far left (for what I need, anyway). I haven't found any way to move it right a few pixels so that it's actually *within* the SashForm box. I want it to look similar to the right side.

Is this possible?

P.S. This is my first post on the mailing list, so hi! I'm new to SWT, and love it so far. But I'm still a newbie, so bear with me. :)
